Recycling nickel-rich cathodes toward structural and functional circularity: a perspective

Key Points

• To explore methods for recycling nickel-rich cathodes focusing on value retention through recovery and restoration.
• Proposed a classification system for recycling nickel-rich cathodes.
• Outlined three key processes: elemental recovery, structural preservation, and functional restoration.
• Elemental recovery enhances metal inventory.
• Structural preservation maintains the integrity of the layered framework.
• Functional restoration leads to improved performance of recycled materials.
